+1 for those who have mentioned the AF Zoom Micro-Nikkor 70-180 mm f/4.5-5.6 ED. It was only made for about 5 years, Nikon ending production in about 2005. It never really got popular until they stopped making it. I found a really clean copy for $2,000 on eBay several years ago and have never regretted the purchase. Of the current lenses, my favorite is the 105VR. While I haven't really done it seriously, don't forget focus stacking is all the rage now. I find the D800 is not all that good for depth of field as it is necessary to limit the minimum aperture to around f8 or so due to diffraction. That sharp sensor doesn't come without issues!
